uploadify 设置了uploadLimit：5，当上传的图片数量大于5的时候，因为我重写了onUploadError进行提示，总是会弹出一句：The upload limit has been reached (...).

查看了源码发现

switch (errorCode) {
case SWFUpload.UPLOAD_ERROR.HTTP_ERROR:
errorString = 'HTTP Error (' + errorMsg + ')';
break;
case SWFUpload.UPLOAD_ERROR.MISSING_UPLOAD_URL:
errorString = 'Missing Upload URL';
break;
case SWFUpload.UPLOAD_ERROR.IO_ERROR:
errorString = 'IO Error';
break;
case SWFUpload.UPLOAD_ERROR.SECURITY_ERROR:
errorString = 'Security Error';
break;
case SWFUpload.UPLOAD_ERROR.UPLOAD_LIMIT_EXCEEDED:
alert('The upload limit has been reached (' + errorMsg + ').');
errorString = 'Exceeds Upload Limit';
break;
case SWFUpload.UPLOAD_ERROR.UPLOAD_FAILED:
errorString = 'Failed';
break;
case SWFUpload.UPLOAD_ERROR.SPECIFIED_FILE_ID_NOT_FOUND:
break;
case SWFUpload.UPLOAD_ERROR.FILE_VALIDATION_FAILED:
errorString = 'Validation Error';
break;
case SWFUpload.UPLOAD_ERROR.FILE_CANCELLED:
errorString = 'Cancelled';
this.queueData.queueSize -= file.size;
this.queueData.queueLength -= 1;
if (file.status == SWFUpload.FILE_STATUS.IN_PROGRESS || $.inArray(file.id, this.queueData.uploadQueue) >= 0) {
this.queueData.uploadSize -= file.size;
}
// Trigger the onCancel event
if (settings.onCancel) settings.onCancel.call(this, file);
delete this.queueData.files[file.id];
break;
case SWFUpload.UPLOAD_ERROR.UPLOAD_STOPPED:
errorString = 'Stopped';
break;
}

这句是不是应该去掉啊 。
